Why Is My One Tooth Suddenly Sensitive? Sudden Tooth Sensitivity

One tooth suddenly sensitive? Don’t ignore the issue – see your dentist right away for an evaluation. They can help determine the cause and recommend the best treatment plan for you.

What Is Dentin Hypersensitivity?

Dentin hypersensitivity is a common dental issue that causes teeth to become overly sensitive to certain stimuli such as hot or cold foods or beverages, touch, or even air. This condition can be caused by several different factors. Today we will discuss some of the most common causes, as well as how dentists can help you treat this condition. One tooth suddenly sensitive? Check out what to do!

One Tooth Suddenly Sensitive: Periodontal Disease

One of the most common causes of sudden tooth sensitivity is periodontal disease. This condition can be caused by plaque buildup, poor oral hygiene habits, or even genetics. It is a chronic inflammatory condition that affects the gums and jawbone around the teeth. Periodontal disease can cause tooth sensitivity as well as receding gums, bad breath, and even tooth loss.

Exposed Root Canal

Another possible cause of one tooth suddenly becoming sensitive is the exposure of the root canal. This can occur when decay or trauma to the tooth causes a loss in a protective layer of enamel, exposing the dental pulp and nerves inside the tooth. Root canals are usually treated with a filling or crown, but if left untreated they may become infected and lead to pain, sensitive teeth, and even tooth loss.

Acid Reflux

A third possible cause of one tooth suddenly becoming sensitive is acid reflux. This condition can irritate the nerves and tissues in the mouth, causing them to be overly sensitive. Acid reflux symptoms include heartburn, regurgitation of food, chest pain, and a sour taste in the mouth.

Acidic foods, smoking, and alcohol consumption are all possible causes of acid reflux. If you are experiencing sensitivity in one tooth, be sure to consult your dentist for proper diagnosis and treatment recommendations.

Tooth Decay

One tooth suddenly sensitive – what to do? Another possible cause of one tooth suddenly becoming sensitive is tooth decay. Tooth decay occurs when plaque buildup and poor oral hygiene lead to bacterial infection in the dental pulp. This infection can irritate the nerves inside the tooth, causing discomfort and sensitivity or even potential nerve damage.

Receding Gums

Receding gums occurs when gum tissue pulls away from the teeth, exposing the roots and increasing their sensitivity to stimuli such as pressure, hot or cold drinks, or even air. Receding gums can occur due to genetics, poor brushing habits, and other oral hygiene issues.

Cracked Tooth

In some cases, if the tooth is cracked or chipped, this may also lead to sensitivity in just one tooth. Cracked teeth can occur due to trauma to the mouth, old age, grinding and clenching habits, or even an underlying condition like bruxism. If one of your teeth suddenly becomes sensitive, and you are experiencing pain when biting down or chewing, it is important to see your dentist right away for an evaluation.

Tooth Whitening

Finally, if you notice that your one tooth suddenly becomes sensitive when undergoing a teeth whitening treatment at home or in the dentist’s office, there may be something else going on. It is important to consult your dentist right away, so they can determine if the sensitivity is related to tooth damage or decay, or another underlying condition such as gum disease.

Sudden Tooth Sensitivity Treatment

There are several different treatment options that your dentist may recommend if you are experiencing sensitivity in one tooth. These include proper oral hygiene, fluoride treatments and rinses, dental fillings or crowns to protect the teeth, or even root canal therapy if the nerve is infected.

Additionally, there are some steps you can take at home to reduce sensitivity, such as avoiding high-acid foods and drinks, quitting smoking or chewing tobacco, and practicing good oral hygiene habits. Whether you are undergoing treatment for periodontal disease, acid reflux, or another condition that is causing tooth sensitivity in just one tooth, it is important to follow your dentist’s recommendations closely.


Desensitizing toothpaste or gels and special toothbrushes can also be used to reduce the exposure of dental nerves and relieve tooth sensitivity. These products contain ingredients like potassium nitrate, which help block the pain signals that stimulate the nerves in your teeth.

Overall, if you notice that one tooth suddenly becomes sensitive, it is important to consult your dentist as soon as possible for proper diagnosis and treatment recommendations. Whether you have experienced trauma or decay, sensitivity in one tooth can be a sign of an underlying condition that needs to be addressed right away. With the right treatment plan, you can enjoy lasting relief from sensitivity and keep your smile healthy for years to come.
